Adaptive Filtering Procedure

(for MATLAB®)

General Notes

Physiological data often requires the exclusion of artefacts
and additional ectopic values (e.g. for heart rate variability:
ventricular premature complexes). Here we give an adaptive filtering procedure
for automatic artefact removal. The advantage of this algorithm is
the spontaneous adaptation of the filter coefficients due to sudden
changes in the time series (e.g. sudden heart rate increase).
